[Newbies] Re: >> notation

[Klaus D. Witzel]

Hi Another Dave,

the >> is used in an informal printout (or in code snippets posted), like  
in

  UndefinedObject(Object)>>doesNotUnderstand: #asTraitComposition

Do this in a workspace: (nil asTraitComposition) and you'll get lots of >>  
printed out.

But when using >> as message selector,

  (Object>>#doesNotUnderstand:) inspect

results in the CompiledMethod.

HTH.
